Black Rhino

Diceros bicornis

Status: Critically Endangered

Population: 5,000 – 5,400

Killed in large numbers by European hunters and settlers, today rhinos are an important source of income from ecotourism in places like Namibia. World Wildlife Fund says this species has made a strong comeback from the brink of extinction, but poaching and black-market trafficking of rhino horn continues to threaten recovery.
